SPECIFICATION forming part of Letters Patent No. 624,532, dated lllliay9, 1899.

Application filed May 5,1898. SerialNo. 679,782. (No model.)

To all whom it may concern:

Be it known that I, JAMEs A. PARK, of White I'IouseStation, in thecounty of Hunterdon, State of New Jersey, have invented certain new anduseful Improvements in Fence-Machines, of which the following is acomplete specification, reference being had to may obviously be used formanufacturingthe fabric in factories.

My improvements consist generally in means for facilitating the forwardmovement of the machine and for steadying it in its upright position, inimproved means for twisting the weft-wires, and in other details,whichwill be hereinafter more fully pointed out.

In the accompanying drawings, which illustrate my invention, Figure I isa perspective view of my improved fencing-machine in 0p erativeposition, the twister-wheels and bob-. bin-holders being omitted. Figs.11 and III are side and top plan views, respectively, of the upperportion of Fig. 1, illustrating the manner of moving the machineforward. Fig. IV is a side view of several of the twisterwheels,bobbin-holders, and shafts. Fig. V is a central vertical section,enlarged, through two of the twister-wheels shown in Fig. IV. Fig.VI isa front View of three of the twisterwheels and apair of bobbin-holders.FigVII is a perspective view of two of the twisterwheels. FigVIII isaside view of part of the intermeshing cogs of the twister-wheels andthe stem of the bobbin-holder in engagement therewith, the latter beingshown in cross-section. Fig. IX is a perspective view, partly brokenaway, of one of the hollow shafts through which the warp-wires extendand which support the twister-wheels. Fig. X is a central longitudinalsection through one of the bobbins and bobbin-holders. Fig. XI is ahorizontal section, partly in plan view, taken centrally through thedriving-shaft of the machine. Fig. XII is a section on the line .60 :0

of Fig. III. Fig. XIII is a vertical longitudinal section through theupper part of the forward standard of the machine, showing thewire-clutch mechanism. Fig. XIV is a central vertical section throughthe clutch shown in Fig. XIII. Figs. XV, XVI, and XVII are perspectiveviews of parts of the clutch. Fig. XVIII is a front perspective view ofthe base of a bobbin-holder. Fig. XIX is a similar, view of one of thepivoted dogs for connecting the bobbin holder to the twister-wheels.Fig. XX is a similar view of one of the bobbin-clamps. Fig.'XXI is asimilar view of one of the bobbins. Fig. XXII is a section,

on the line y y of Fig. II, and Fig. XXIII is a section on the line 2 zof the same figure.

Referring to Fig. I of the drawings,.1 and 2 indicate verticalstandards, by which the working parts of the machine are supported. Therear section of the machine consists of a standard 2,longitudinallydivided in the plane of the warp-wires, the two parts of the standardhaving opposing recesses, as shown, on 1 their faces, within which thehollow station; ary shafts 3, 3, and 3 are clamped by means of 13011334passing through the standard and between each pair of shafts. Thestationary shafts are each secured to one part of the standard by meansof screw-bolts 5, having their heads within and flush with the interiorof the shafts and the screw-th readed end passing out through thestandard and secured by a nut. The drive-shaft 3 is mounted in suitablebearings, (shown in Fig. XL) and this.

arms 8, extending in a plane at right angles to the shoe, these armsbeing provided at their 7 outer extremities with a 'thumb-screw9, bymeans of which they may be drawn together to form a clamp. The arm maybe connected to the side of the upright 2 by a suitablebrace 10. Beneaththe arms 8 and extending at right angles to the machine is a shaft 11,

' screws and washers 26.

connected by pins 17 to cranks 27, secured to hinged to the shoe, so asto swing in a vertical plane, and carrying at its outer extremity thewheel 12. A curved link 13 is rigidly connected to the shaft 11 near itsouter end and extends between the two parts of the arm 8, the set-screw9 passing through the opening in the link. By means of the arrangementjust described the wheel 12 may be arranged at-different angles, so asto maintain the machine in a vertical position under all conditions.

The standard 1 of the forward section of the machine also consists oftwo parts 14 and 15. This standard may be much shorter than the rearstandard 2. As shown in the drawings, the part 15 extends below the part14, and a large wheel 16, journaled in this extension, supports thestandard. Certain of the hollow stationary shafts-as, for instance, theshafts 3 -are longer than the others and extend for ward between theopposing sides 14and 15 of the standard 1. These shafts pass freelythrough guides 20, which are secured to the (shown in section in Fig.XXIL) having vextically-projecting studs 23, upon which are journaledthe ends of links or pitmen 24,'the latter being held in place by meansof set- The links 24 are the opposite ends of a vertical shaft 28. Thecrank-arms 27 are each provided with a series of holes 18 for thereception of the link-pins, so that the movement of the links may begraduated. The shaft 28 is journaled in boxes 29, mounted upon theintermediate stationary shafts 3 and 3 and secured to a brace 30,extending between the shafts 3". Abeveled gear 31, rigidly secured tothe upper part of the shaft 28, engages a beveled gear 32,

' supported in a suitable manner upon the uppermost journal-box 29. Asshown in Figs. 1 and XII, the gear 32 has a central bore in its innerface, which engages with a projecting stud 33 upon the side of thejournal-box 29, and its shaft 34is supported by an angleiron 25, securedto the top of the journal-box. A turning crank 36 is connected to theshaft of the bevel-wheel 32. The brace-bar 30 extends between the upperand lower ext-ended shafts 3" and is connected to the severaljournal-boxes, so as to make the machine more rigid. Its upper end 37 iscurved forward, so as to clear the gear3l, and is secured rigidly to theuppermost shaft 3 v i It will be seen that by turning the crank 36 theshaft 28 will be rotated and the links 24 will be given a reciprocatingmotion through the medium of the cranks 27. At each semirevolution ofthe shaft 28, therefore,the standard 1 will be forced forward on itswheeled support a distance equal to the' diameter of the circledescribed by the crank-pin 17 from 'clusive,and described below.) Theseclutches slide freely over the warp-wires during the forward movement ofthe standard 1, but grip the wires whenever the standard commences tomove in the opposite direction. It will be seen, therefore, that thecontinuous movement of the crank 36 through a complete revolution or arocking movement will of necessity draw the rear section of the machinetoward the front section,'since the latter cannot move backward. In thismanner the movement of the machine is greatly facilitated, as theforward and rear parts of the machine are moved separately and steadilyand no tracks are required. The manner of moving the machine forward isclearly indicated in Figs. II and III. By adjusting the crank-pins 17the movement may be regulated so as to wind the weft-wires at differentintervals. I

The clutches above referred to (illustrated in Figs. XIII to XVII,inclusive) consist each of a base-plate 40, having a projecting stud 41at its lower extremity and a clip 42 at the top, and a spring-pawl 43,depending from a bearing-piece 44, the latter being eccentricallymounted upon a bolt 45, which passes through the base-plate and theupright 14 and is secured by a nut 46 upon the outside of the upright.The bearing-piece 44 is surrounded by a boss 47 and the latter in turnby a flange 48. The pawl 43 has on its lower and forward side a flange49. A coiled spring 50 surrounds the boss 47, its ends resting withinthe catch 42 on the base-plate and the flange 49 upon the pawl. The endof the pawl normally hangs directly above the pin 41, and the pawl isadjustable vertically by means of the eccentric bearing 44, so as toadapt the clutch to wires of different gage. The warpwires pass betweenthe pawl and the pin 41, and it will be seen that when the standard 1 ismoved forward the pawls will glide over the wires, but will immediatelyand firmly engage the wires as soon as a backward pull is exerted uponthem. The warp-wires are held against the pins 41in proper relation toeach other by means of bolts 51, passing through thestandard 1 inadvance of and .engagement with the pawl when the shaft has been rotatedto the desired extent. As shown in the drawings, the stops are arrangedso that the shaft can only make two and onequarter revolutions in eitherdirection. The shaft is driven bymeans of beveled gears and 61, whichare operated by a crank 62.

The twister-wheels, as shown in Figs. IV, V, VI, and VII, are eachformed with front and rear skeleton plates, the front plate 63 beingflat and the rear plate 64, as shown, extending outward toward thecenter. Each of the stationary shafts is provided with a collar 65, bymeans of which the wheels are maintained upon the shafts. In placing thewheels upon the shafts the collars G5 are first inserted within therespective wheels and the two are then slipped overthe end of the shaft.The collar is then secured to the shaft by a set-screw 66. The wheelswill then be free to revolve on the shafts and the collars will preventlateral displacement. The wheel upon the driving-shaft 3 is rigidlysecured to the shaft by means of a key or set-screw. As shown in thedrawings, one tooth is omitted from each of the twister-wheels, itsplace being supplied by two small separate auxiliary teeth 67, whichextend slightly above the pitch-line. I designate the teeth 67 as Fseparate teeth because of the fact that they are separate both from eachother and from the remaining cog-teeth. A web or flange projection 68,arranged in rear of the gear-teeth, extends across the space betweeneach of the auxiliary teeth 67 and the adjacent cog. The

opposed faces 69 of the webs, and also the faces of the teeth 67, arecurved to conform.

openings 73, arranged on either side of the axis and in line with thespace 74 between the. auxiliary teeth 67.

The bobbin-holder or twister consists of a base-plate 75, having curvedupper and lower edges 7 6 and 77, respectively, a tubular extension 78,projecting rearwardly from the center of the plate, a pair of parallelforwardly-projecting arms 79,arranged upon one side of the plate, and asimilar pair upon the opposite side. The plate is also formed with twocurved oblong openings 81, arranged near the top and bottom, as shown.Each pair of arms 79 and 80 is provided with registering perforations 82midway of the arms and similar perforations 83 at the ends. In Fig. XIX,I have showua dog consisting of a bar 84, having a longitudinal groove85, a pair of perforated ears 86, projecting from one end at an angle tothe bar, and a peculiarlyformed head 87, projecting in a plane parallelto that of the cars 86. The head, as shown,

projecting partly above the bar84c, its outer surface 88 being curved orinclined and the faces 89 and'90 being straight. A narrow flange 91,having its outer face in the same plane as the face 90, extendsdownwardly from the bar. Two of these dogs are connected to the arms 79and 80, respectively, by means of pivot-pins passing through theperforated cars 86 and the perforations 82 in the arms. When the dogsare in place, their heads will swing into the openings 81 in thebase-plate, as shown in Figs. V and VI, the flange 91 limiting themovement of the dogs. The dogs are normally held in this position bymeans of springs 92, which are wound around the pivot-pins 93, one endof the spring resting within the groove and the other end of the springbeing hooked around the stud-94 upon the end of a spool-clamp 95, one ofwhich is pivoted in the ends of each pair of arms 79 and 80. It will beseen that the springs 92, while normally forcing the dogs into theopenings 81, will also press the spool-clamps 95 toward each other.These clamps are each formed with a stud 96, which projects into theopenin gin the bobbin 97, and a flange 98, which presses against the endof the bobbin with sulhcient force to prevent thespool from turningloosely and. too freely unwinding the weftwire. The wire is fed from thebobbin through the tubular stem 7 8 in the rear of the bobbin-holder.This stem I prefer to fitwith a screw-threaded bushing 99,0f brass orother metal different from theweft-wire, so as to avoid friction as muchas possible. This bushing is formed with a flange 100. As shown in Fig.VIII, the stem 78 is hexagonal in cross-section, the sides 101 and 102being adapted to fit against the wheels within the spaces between thecogs and the remaining sidesbeing formed in the shape of two cogs withtheir bases abutting. This stem is adapted to fit within the space 74between the auxiliary teeth 67, and when the wheels intermesh at thatpoint, as shown in Fig. VIII, the curved sides of the stem 78 will cutthe cogs of the adjacent wheels upon the pitchline.

In assembling the machine the extensions 7 8 of the bobbin-holders areplaced within the spaces 7 4, the base-plate of each bobbin-holder lyingnext to the flat front faces of the two adjacent gear-wheels. hen thespaces 74 are in alinement, the heads 87 of the dogs will projectthrough the openings 81 in the baseplate of the bobbin-holderinto therectangular openings 73 of the adjacent twister-wheels, as shown inFigs. V and VI. In this position the bobbin-holder will be anchored bystationary disks 105 upon the shafts which are fitted close to thebase-plate of the bobbin. The disk upon the driving-shaft 3 is securedto the standard 2 by a sleeve, as shown, while the disks upon thestationary shaft are so: cured by set-screws to said shaft. These disksare cut away on their upper and lower consists of a part arranged at anangle to and edges 106 in the are of a circle corresponding with thecurvature of the outer walls of the openings 81 in the base-plates ofthe bobbinholders. The bobbin-holder base-plate is in width about equalto the distance between two adjacent shafts, and the edges 76 are formedin the arc of a circle whose radius is approximately equal to thedistance between the center of one shaft and the outside of an adjacentshaft.

It will be seen that when the wheels are in the positions shown in Figs.V and VI the dogs are maintained within the openings in the base-plateand twister-wheels only by the tension of the springs 92; but if theupper gear A in Fig. VI be assumed for the purposes of illustration tobe the driving-gear rorating in the direction of the arrow the wall ofthe lower opening 73 in this gear coming into contact with the inclinedsurface 88 of the dog will force the latter out of engagement with saidopening, whereas the wall in the upper opening of the gear B belowcoming into contact with straight face 89 of the lower dog will draw thebobbin-holder forward until the face 90 of the dog passes under the disk105, adjacent to the wheel B. The bobbin-holder will therefore bedisengaged from the upper wheel A and will be carried around by thewheel B, being held in engagement therewith by the flange 105 and theflange 100 upon the stem 78. In a similar manner the lower bobbin-holderwill be carried around by the wheel B, and the weftwires will be twistedaround the warp-wire passing through the shaft upon which the wheel B ismounted in the usual way. By reversing the direction of the wheels thebobbins instead of passing around the wheel B will pass around theadjacent wheels.

As stated above, I prefer to rotate the shafts about two and one-quartertimes in each direction in order to twist the wires twice, thequarter-turn being allowed to compensate for backlash in the gears. Thismovement is li mited by the worm 56, pawl 57, and stops -59. (Shown inFig. XI and previously described.)

In operation after the machine has been moved forward a step in themanner already described by turning the crank 36 the gears are operatedto twist the weft-wires upon the warp-wires by turning the crank 62. Themachine is then moved forward another step and the gears turned in theopposite direction to effect the twisting of the weft-wires upon theadjacent warp-wires, and so on.

It will be noticed that in my machine the bobbin-holders or twisters arein front of the twister-wheels and that the weft-wires are fed outcentrally through the tubular stems 78, which at all times firmly restwithin the spaces formed in the gear-teeth. At the time when thegreatest lateral strain is exerted to, of means for moving both sectionsforward by independent steps, .substantially as set forth.
